The catalytic tests showed that this type of catalyst is active for nitrate reduction. The use of polymer support improves the selectivity of the catalyst toward nitrogen formation compared to a classical support, and avoids the apparition of intermediate nitrite. These better performances of the catalysts supported on electroactive polymers were explained by the ion-exchange properties of the conducting polymers. The most selective catalyst was Pd–Sn/PPy catalyst prepared by successive impregnation. The lower selectivity obtained with the Pani-supported catalyst was explained by the capability of this polymer to directly reduce nitrate into ammonium ions.Submitted by Bruna Lessa (lessbruna@gmail.com) on 2012-06-19T13:53:17Z No. of bitstreams: 1 (78)1-s2.0-S0926337309003580-main.pdf: 499530 bytes, checksum: 18fd7635518481562d3745b99b4b1cf3 (MD5)Made available in DSpace on 2012-06-19T13:53:17Z (GMT).
